METHOD OF AND APPARATUS FOR PREPARING REGISTERING IMPRESSION-FORMS.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed March 1, 1915. Serial No. 11,264.

paring registering impression forms and is particularly an improvementupon the method and apparatus described and claimed in an earlierapplication,

By the invention hereinafter described it is possible to rapidly arrangethe movable members of an impression form, such as is employed inprinting, embossing, dieing and creasing, lithographic or similar work,so as to insure accurate register of an impression therefrom with animpression or impressions from a similar form or forms.

According to the method described in the earlier application referredto, a representation. of an impression from the form to be made up, forexample, is supported in a horizontal position above thework table andan image of a sufficient portion thereof is projected onto a form onsaid table as a guide by which the proper or correct position of thecorresponding movable member of the form may be determined. It has beenfound that by the method hereinafter described the apparatus required tocarry out the method of said earlier application may be considerablysimplified.

In the accompanying drawings: Figure 1 is a perspective view of anapparatus embodying the present invention; Fig. 2 is a transverse,vertical sectional view of the apparatus; Fig.3 is a horizontal,section, view; Fig. 4 is a detail sectional view, on an'enlarged scale.

Referring to the drawings, it will be seen that the embodiment of theinvention therein illustrated comprises a substantially rectangularframe 1 adapted to be supported on the usual work or imposing stone ortable 2 and provided at its top with a glass plate 3. The frame 1 may beconstructed in any suitable manner and the transparent top thereof heldin place by any desired means.

A carriage-like frame 4 is mounted to move along side rails 5 secured toend posts of the frame 1, one or both of said rails being provided witha suitable rack 6 with which meshes a pinion 7 secured on a shaft 8carried by the carriage 4. By actuating suitable hand wheels 9 securedon the ends of the shaft 8, the carriage 4L and all parts supportedthereon may be adjusted longitudinally of the rails 5 The carriage 4 isprovided with a centrally arranged housing or casing 10 that issupported to move thereon in a direction transverse to the length of therails 5 and the line of movement of the carriage by the shaft 8. Saidhousing includes similar upwardly and downwardly directed section eachof which terminates in a projection device or lens tube 11. Within thecasing 10 is arranged a translucent plate 12, preferably of groundglass. Inspection of the images projected on the ground glass plate 12by the lenses in the tubes 11 may be had through openings provided inopposite walls of the upwardly extending portion of the casing 10, saidopenings being preferably surrounded by outwardly projecting tubes 18 ofsuch size as to receive an operators face.

As it frequently happens that the detailof the images appearing on theground glass plate 12 is small, a magnifying glass 14 is preferablyarranged within the casing 10, adjacent each of said openings, each ofthe glasses being supported so that it can be readily moved to and froma position across the adjacent sight or inspection opening of thecasing. The handle 15 of each magnifying glass, as shown, extends to theoutside of the housing so that the device may be readily manipulated bythe operator, as desired. The housing excludes light from the groundglass plate 12, except such as passes through the lens tubes 11 and theinspection tubes 18. Either of the latter may be closed by a suitablecap and the other is practically completely closed when the apparatus isin use. Means are provided whereby objects Within the fields of the lenstubes may be illuminated, if desired. As shown, the housing or casing 10has mounted thereon suitable electric lights and reflectors 16, 1.7 forthis purpose.

In using the apparatus a drawing 21 or other representation of animpression from the form to be made up, or a sheet bearing suitable andsufiicient registering detail to indicate the proper relative positionsin a form of the movable part or parts thereof, is placed upon the glasstop plate 3. The carriage is then adjusted so that images of portions ofsaid guide sheet and the form 20 are displayed on the ground glass 12,the sheet and form, or the areas thereof within range of the lenssystems, being illuminated if desired or necessary. The operator 'thenadjusts or shifts the movable member of the form the image of which, orof a sufficient portion of which, is displayed on the ground glass 12until such image and the image thereon of the corresponding part of thesheet 21 are properly superimposed. The movable member of the form isthen secured in position. The carriage and means thereon are so arrangedthat the lens tubes can be easily shifted so as to bring any desiredportion of the areas of the form and guide sheet within the range of thelens systems.

It will be evident that there can be considerable variation in thedetails of the apparatus herein illustrated without departing from thespirit of the invention.

The term impression form is intended to include any holder, container,or base adapted to receive one or more movable members and retain thesame in any adjusted position, so that impressions can, by aid of asuitable press, be obtained therefrom. In particular the invention isemployed in preparing forms for multi-color printing, embossing andcutting or creasing blanks or sheets which have been or are to beprinted and in which careful register of successive operations isnecessary.

Having thus described the invention, what is claimed .and desired to besecured by Letters Patent is:

1. The herein described method of determmmg the correct position in animpresslon form of a movable member comprlsing superlmposing in registeran image of a sufiicient portion of such member on an image of acorresponding part of a representation of an impression from the form.

2. The herein described method of determnnng the correct position in animpresslon form,of a movable member comprlsmg arranging a suitablesurface in such relatlon to an impression form and a representation'ofthe impression to be produced by the form that images of portions ofboth sa d representation and form will be recelved thereon andmanipulating said movable member until the image on said surface ofsuflicient registering detail thereof coinc1des with the image ofcorresponding parts of the representation of an impression to beobtained from the form.

7 The herein described method of deternnmng the correct p sion form of'a' mova 1e member comprising arranging a translucent plate between theosition in an impres form and a representation of an impression to beproduced by the form, projecting onto opposite faces of said plateimages of portions of said form and representation, and manipulatingsaid movable member until the image of sufficient registering detailthereof on the plate coincides with the image thereon of correspondingparts of the representation of the impression from the form.

4. The combination with a support foran impression form, of means forsupporting a guide sheet or representation of an impression from such aform, and means adapted to superimpose images of corresponding parts ofsaid sheet and a form on the support, to determine the correct pocorrectposition of a movable impression member in such form.

6. The combination with a support for an impression form, of means forsupporting a guide sheet, a casing or housing mounted to move relativeto both said sheet and form supports, and two lens systems carried bysaid casing and adapted to display on a common surface images ofportions of a guide sheet and a form on said supports, for the purposedescribed. 1

7. The combination with a support for an impression form, of means forsupporting a guide sheet, a casing or housing mounted to move relativeto both said sheet and form supports, a translucent plate within saidhousing, and two lens systems carried by the housing and adapted torespectively display on said translucent plate images of portions of aguide sheet and a form on said supports, for the purpose described.

8. The comblnation with a support for an impression form, of means forsupporting a guide sheet in a horizontal position above said support, acasing or housing arranged in plane's between sald supports and movablelongitudinally and transversely there- Q of, said housing being providedwith an interior translucent plate and a lateral opening through whichsaid plate is visible, and two lens systems carried by the housing andadapted to respectively display on the translucent plate therein imagesof ortions of a guide sheet and impression orm on said support, for thepurpose described.

9. The combination with a support for an impression form, of means forsupporting a guide sheet in a horizontal position above sa d support, acasing or housing arranged 1n planes between said supports and movablelongitudinally and transversely thereof, said housing being providedwith an interior translucent plate and a lateral opening through Whichsaid plate is visible, two lens systems carried by the housing andadapted to respectively display on the translucent plate therein imagesof portions of a guide sheet and impression form on said supports, forthe purpose described, and
